duplicate-record-review

duplicate-record-review is a skill for Claude Code, Codex from spiralcrew-ou/profilespider-agent-skills. It costs 48 tokens per session (450 once invoked), scanned A, original, MIT.

A review tool that finds records that may describe the same person or company. It compares available identifiers and reports matching evidence, conflicting fields, confidence, and a suggested record to keep.

In plain words
What is it for?
Checking contact or company lists for duplicates, grouping likely matches, choosing the more complete surviving record, and preparing a merge plan.
Why use it?
It helps prevent duplicate profiles, repeated outreach, and messy data after lists are combined or collected again. It recommends changes for human review rather than merging records automatically.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

duplicate-record-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Duplicate Record Review

Purpose

Identify likely duplicate profiles or companies using available record evidence.

When to use this skill

  • De-duplicating a merged or re-scraped list
  • Catching the same company under different names
  • Preventing double outreach to one contact
  • Producing a reviewable merge plan

When not to use this skill

  • The records share no comparable identifiers
  • You need an irreversible automatic merge (always review)
  • The list is already known to be unique

Required inputs

  • A list of company or profile records

Optional inputs

  • Match keys to prioritize (domain, email)
  • A confidence threshold
  • Fields that must match exactly

Rules

  1. Describe matches as likely unless an exact deterministic key matches.
  2. Report match confidence and the evidence behind it.
  3. Never auto-merge; recommend and flag for review.
  4. List conflicting fields explicitly.
  5. Prefer the most complete record as the survivor.

Process

  1. Compare records on available keys.
  2. Group likely duplicates.
  3. Assess confidence and list matching/conflicting fields.
  4. Recommend a survivor and merges.
  5. Set manual-review status.

Output format

Return one record per duplicate group with the following fields:

  • duplicate_group
  • match_confidence
  • matching_fields
  • conflicting_fields
  • merge_recommendation
  • manual_review_status

Validation

  • Confirm only exact key matches are called certain.
  • Confirm conflicts are listed for each group.
  • Confirm no merge is performed automatically.

Limitations

  • Without unique keys, matches are probabilistic.
  • Distinct entities can share names; review before merging.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
